You can open up access to any IP or IP range, from the web panel:
Just edit the user, make the change at the bottom of the page, and submit. A few hours later, it'll take effect.
Note that you can't open it up to 'localhost', since EVERYONE is localhost (in the words of a great robed man, "from a certain point of view").
In any case, you'll actually have to specify an IP address or range of IPs to open up. If you don't know what to put here, you'll probably have to contact your ISP and see what IPs you're likely be be connecting from.
